Re: What is not objects in Python? process wrote: What is not an object in Python? Everything that is not part of Python's syntax is an object, including all string and number types, classes, metaclasses, functions, models, code and more. It's technically not possible to have somethi...

In Python, objects are instances of classes. A class is a blueprint or template that defines a set of attributes (variables) and methods (functions) common to all objects of that class. Data and behavior are encapsulated in objects, which represent real-world entities or abstract concepts. He...
The terms "type" and "class" are interchangeable: list, dict, tuple, int, str, set, and bool are all classes. You'll certainly use quite a few classes in Python (remember types are classes) but you may not need to create your own often. To track your progress on this Python ...
In Python classes, instance variables are variables that are unique to each instance (object) of the class. They are defined within the class and used to store data specific to individual objects. It is possible for objects of the same class to have their own independent data through instance...

Object-oriented programming (OOP) is a programming paradigm. It's based on the idea of grouping related data and functions into "islands" of information. These islands are known as objects. No matter which paradigm is used, programs use the same series of steps to solve problems: Data input...
1. Type and OOP¶ Everything is an object in Python, including classes. Hence, if classes are an object, they must be created by another class also called as Metaclass. So, a metaclass is just another class that creates class objects. Usually,typeis the built-in metaclass Python uses ...
One of the cool things you can do with auto-implemented properties is specify initializers that set the property’s default value when the constructor runs. A common scenario with entity classes, for example, sets the primary key to something like -1 to indicate that it’s in an unsaved sta...
The behavior in first and second snippets is due to a CPython optimization (called string interning) that tries to use existing immutable objects in some cases rather than creating a new object every time. After being "interned," many variables may reference the same string object in memory (...
